The # assert fails because we have unlocked the PTE in text_area_cpu_up_mm(). # # Instead leave the PTE locked and only unlock it when we tear down the # patching_mm for the CPU. That avoids the assert failing, and nothing # else should be using the PTE so leaving it locked is arguably more # correct. # # Fixes: c28c15b6d28a ("powerpc/code-patching: Use temporary mm for Radix MMU") # Reported-by: Nathan Chancellor <nathan@kernel.org> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 1562551aec8bb15974c69ee79b8da8cc688e7340 # < make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-next_corenet32_smp_defconfig_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- corenet32_smp_defconfig # < make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-next_corenet32_smp_defconfig_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-next_corenet32_smp_defconfig_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-next_corenet32_smp_defconfig_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/drivers/net/ethernet/freescale/dpaa/dpaa_eth_sysfs.c: In function 'dpaa_eth_show_addr': /kisskb/src/drivers/net/ethernet/freescale/dpaa/dpaa_eth_sysfs.c:21:33: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] 21 \| (unsigned long long)mac_dev->vaddr); \| ^ Completed OK # rm -rf /kisskb/build/powerpc-next_corenet32_smp_defconfig_powerpc-gcc11 # Build took: 0:03:21.300696
